Title: Process and device for degumming ramie and other similar fibres
IPC: D01C1/02
Filed: 1935-09-14
Abstract: <PICT:0447013/IV/1> <PICT:0447013/IV/2> In a process for degumming ramie or similar fibre, the fibre is submitted to a preliminary short treatment in an open kier with a hot dilute soap solution (gradually raised to the boiling point) to soften the gummy substance and is subjected to a suitable vibratory motion produced by mechanical means in such a manner as to transmit the vibration to the entire mass of fibre, to emulsify the softened gummy substance and shake it free from the fibre.  It is advisable to soak the fibre in water for several hours beforehand to remove some of the colouring matter.  The fibre may be raised to boiling point in a 1 per cent soap solution and then subjected to the vibratory treatment in cold, preferably running, water, or the vibratory treatment may be applied while the fibre is being heated in the soap solution and maintained while the soap solution is rapidly brought to the boiling point.  The fibre is then withdrawn, rinsed and vibrated for a while in clean boiling water.  Rinsing and bleaching, e.g. with calcium hypochlorite complete the treatment.  The apparatus for performing the treatment comprises a rigid openwork circular cage with base A<11>.  To two of its upright rods C<1> and C<111> are fixed the vibrating means. These consist of supporting blocks E, E<1> rigidly connected to the cage and carrying axles F, F<1> on which revolve eccentric discs G, G<1> which are rotated by pulleys H, H<1>.  The base of the cage is of steel wire netting and carries a number of stainless steel needles solidly attached thereto, and with rounded points.  A layer of fibres is spread on this platform and covered with a tray, Fig. 2, having needles N, N<1> on both its upper and lower sides.  The whole cage is filled with alternate layers of fibres and trays in this manner, the needles of the trays penetrating the layers of fibres, but the trays being separated by distance members. Entanglement of the fibres is prevented by the needles which, however, ensure that the vibration is transmitted to the entire mass of the fibre.

Title: Generator of travelling wave of gaseous-discharge current
IPC: H01J25/38
Filed: 1947-09-22
Abstract: 645,880. Pulse generating circuits. HAZELTINE CORPORATION. Sept. 22, 1947, No. 25745. Convention date, Oct. 4, 1946. [Class 40 (vi)] [Also in Group XL (a)] An arrangement for producing current impulses comprises a plurality of condensers 10... 19, Fig. 1, charged from the D.C. source +B, and a gaseous discharge device 54 having anodes 20 . . . 29, common cathode 30, and triggering electrode 52, for discharging the condensers 10 ... 19, an input pulse on trigger 52 firing the discharge path to anode 20 and the ionization thereby produced firing the next discharge path to anode 21, and so on, so that all the discharge paths fire in sequence. The output is derived at terminals 41<SP>1</SP> ... 50<SP>1</SP> via " sampling " electrodes 31 ... 40. The arrangement may be utilized as a commutating or scanning device. The filling is xenon or argon. The condensers 10 ... 19 are associated with inductances 60 ... 69 to form resonant circuits. Each discharge goes out as the next one ignites, undesirable re-ignition being prevented by giving large values to resistances 10<SP>1</SP> ... 19<SP>1</SP> so that condensers 10 ... 19 recharge slowly. When condenser 10 is recharged, another cycle of operation may be started by applying a second pulse to trigger 52. If the tube is very long, condenser 10 may be recharged before the last condenser 19 has been discharged, in which case the control potential developed at resistor 50 may be used to trigger the tube again. Several " waves " of current may traverse a long tube simultaneously and independently. Some of the output terminals 411 ... 50<SP>1</SP> may be omitted, or only one output terminal may be employed, e.g. for timing an operation with a predetermined delay with respect to the triggering pulse. The igniter 52 may be located centrally in the tube, in which case two " waves " of current may advance in opposite directions. In another modification, Fig. 4 (not shown), the anode structure itself has distributed capacitance and the condensers 10 ... 19 are dispensed with. The anode in this case is two concentric conductive cylinders with dielectric in between, the outer cylinder having some electrical resistance. Specification 650,102, [Group XL (b)], is referred to. The Specification as open to inspection under Sect. 91 suggests that a vapour filling may be used. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,215,784. Stabilizers. ERNST MENZI A.G. 21 May, 1969 [27 May, 1968], No. 25798/69. Heading B7J. [Also in Division E1] The ground-contacting surface of an excavator chassis normally supported on the ground at one end by a pair of undriven wheels 15 and at the other end by feet 18 can be increased by securing a dish or trough-like shell to each wheel or foot. Preferably, each shell comprises a circular, downwardly curved dish 20 having peripherally spaced, upstanding struts 21. Each strut has at the upper end an inwardly projacting arm 22 carrying a threaded clamping spindle 23 that can be screwed down to bear on a foot 18 to cause the shell to be clamped to the foot. Each shell also has two upstanding parallel plates 25 for embracing the sides of a wheel when a wheel is entered on to the shell. The struts of each of two diametrically opposed pairs of struts are connected by cross-strips following the peripheral curvature of the shell. These cross-strips prevent a wheel embraced by the plates 25 from rolling out of the shell. These shells facilitate sliding of an excavator over the ground and improve the stability of an excavator when it is crossing or descending into a trench.
